A small London-based record label is planning to release an album that Leona Lewis recorded before winning the third series of The X Factor in 2006.
UEG Music claim they spent around £70,000 trying to launch the 23-year-old, who is now signed to Sony BMG.
They have already released the album, called Best Kept Secret, in Japan and plan a UK release in January.
But Lewis's lawyers insist UEG does not have her consent or the rights to start selling the record.
